Since the issue with water in your concentrate has been bugging you for many months now, some volunteer should finally set up a quantity of your concentrate, split it in half and mix one half with some amount of deionized water. With repeated activity tests every 1-3 months we could learn whether traces of water are likely going to reduce the shelf life of this concentrate.

Yes, that would be a good test.
Gerald Koch pointed out here that such chemicals will eventually dissolve at room-temperature. So the issue is the water that did not get steamed out.

So getting the chemicals on you will be harmless. The temperatures involved are 85C at most, which is well below what's used for cooking. So there's a lower danger of scalding with D316 than with cooking. Also, D316 can be mixed at 65C (I've done it), reducing scald-risk even farther below cooking-risk.

Overall, I'd say mixing D316 is safer than cooking.
